We sought to determine whether the antihypertensive drug nebivolol has beneficial effects on vascular markers of inflammation and oxidation in obese African-American patients with hypertension when exposed to exercise-induced stress. Forty-three obese, African-American subjects with hypertension were treated with nebivolol (5-10 mg/day) for 8 weeks. Before treatment the subjects underwent an ...

CONTEXT: The magnitude of exercise-induced weight loss depends on the extent of compensatory responses. An increase in energy intake is likely to result from changes in the appetite control system toward an orexigenic environment; however, few studies have measured how exercise impacts on both orexigenic and anorexigenic peptides. OBJECTIVE: The ...

One of the most effective treatments of patients with morbid obesity is laparoscopic Roux-en-Y gastric bypass (RYGB). Sudden weight loss after RYGB for morbid obesity can result in a concurrent decrease in the lean body mass. However, the long-term results (weight reduction and reduced co-morbidities) depend on the postoperative long-term ...

Patients must subscribe to behavioral and lifestyle modifications for continued success after weight loss surgery (WLS). Few data exist about the ideal type, duration, and intensity of exercise for WLS patients. After surgery, should we mandate that patients exercise like a young, lean individual does? To reconcile this, we compared ...
